We had already heard that Target would be carrying the cards, and to that Google adds Radio Shack and Game Stop. Not all stores have them just yet, but you should see them pop up in the coming weeks.

The annoying part of these cards is just how many restrictions Google has in place. First off, you can’t use them towards hardware purchases, like a new Nexus 7. Google gives no explanation for this seemingly arbitrary restriction. You also can’t use the money towards any sort of app subscription, nor magazine subscription. Finally, these are for the US only, and can be neither bought nor redeemed abroad.

If those limitations don’t phase you, and you’re just interested in app purchases and live in the US, you can start shopping for Play gift cards in $10, $15, $25, and $50 denominations.
